Doctors specialized in MRI are called radiologists and they will provide an expert analysis of your images"

MRI machines use magnets and radio waves to make images of the body

"The M.R.I is different from x rays because X-Rays use radio waves and M.R.I Uses magnets"

When a radiofrequency current is then pulsed through the patient, the protons are stimulated, and spin out of equilibrium, straining against the pull of the magnetic field.

"M.R.Is use powerful magnets and force to Move protones around inside your body If it reaches a correct frequency it will spin protons with makes a image to be reviewed"]]> 2021-01-27 17:53:22 UTC https://padlet.com/weldonpollitt/w4nnpfzbgswg3sww/wish/1132963910 Risks to be a whereof B (Categorization) weldonpollitt https://padlet.com/weldonpollitt/w4nnpfzbgswg3sww/wish/1132998894 The magnetic field extends beyond the machine and exerts very powerful forces on objects of iron, some steels, and other magnetizable objects; it is strong enough to fling a wheelchair across the room. Patients should notify their physicians of any form of medical or implant prior to an MR scan.

"The only risks to  be determined today are if you have metal in your pockets or on you it could get attached up do to magnetic in the machine"]]> 2021-01-27 17:59:41 UTC https://padlet.com/weldonpollitt/w4nnpfzbgswg3sww/wish/1132998894 Fun Fact Source: C (Categorization) weldonpollitt https://padlet.com/weldonpollitt/w4nnpfzbgswg3sww/wish/1137866053 On July 3, 1977, the first magnetic resonance imaging (MRI) exam on a live human patient was performed.

"In 1977 the first man ever to use a M.R.I was done successfully"

"When a M.R.I is in use atoms Behave different because how magnets are controlling them has became very useful to to make viewable images with are extremely useful method of seeing inside someone without physical work"

"It cost 800,000 a year per M.R.I Machine to operate"
